1980 Honda CB750K · Piston & Ring Sets Buying guide

Select ring size from the assessed cylinder and piston

The standard piston kit includes a piston, rings, pin and clips, while ring-only sets supply different contents. Decide which components the repair needs, then match the package size to the inspected engine.

Parts to consider

Four kits are specified for all pistons.View part 1979-83 Honda CB750 Piston Ring Set ~ Standard Size Standard-Size DOHC Ring SetRings for one standard-size piston, replacing Honda reference 13011-425-004.

Separate a ring refresh from piston replacement

The standard kit’s listed contents include a piston, rings, pin and clips; the individual ring sets do not list those other components. Review the inspected cylinder and piston with the service work planned. Choose the package for the actual repair rather than treating a ring set as a piston kit.

Use the current engine size, not its age

Previous machining can change the bore size from the original configuration. The standard, first-oversize and second-oversize ring listings cannot identify what is now inside your engine. Confirm the existing piston and cylinder measurements, then match the selected ring specification and quantity to the cylinders being repaired.

Common questions

Does the standard piston kit include pin clips?

Yes. This listing includes one piston, matching rings, a piston pin and a pair of pin clips. It covers one piston, and the description specifies four kits for all pistons on the engine.

How many pistons does one ring set cover?

Each standard, +0.25 mm and +0.50 mm ring listing specifies rings for one piston. Four sets are stated for all pistons. Order according to the cylinders being repaired and keep every set matched to its piston size.

Should I choose oversize rings to compensate for wear?

Choose rings using the assessed bore and piston specification. The oversize label describes a particular size, not a general cure for wear. Have the engine measured and determine the repair requirements before selecting standard or oversize components.
